I'd have to disagree with your statement "That's true for a low dipole
also".  I'm using ELNEC (perhaps not perfect at low elevations), but a
dipole at any height from 30 feet to 100 feet shows about 4-6 db
directivity in the azimuth plane at 30 degrees elevation, where an
inverted vee shows essentially zero.  Not a huge amount obviously, but
clearly different.  Are you seeing something otherwise?
